Question

HELP!!!!!! An Instagram photo is measured ″ 4″ by ″ 4″. A poster enlargement is being printed with a scale factor of 8.5. What is the length of the enlarged sides?

The lengths of the new sides are __________ ″ ″ by __________ ″ ″.

Answer 1

4 by 4 at a scale of 8.5

You just multiply by 8.5 the initial size:

4*8,5 by 4*8,5
That is 34 by 34

Answer 2

The given measurement of the Instagram photo is "4" by "4". And a poster enlargement is being printed with a scale factor of 8.5 .

So on using the scale factor of 8.5 , lengths of new sides are "8.5 *4" by "8.5 *4"

= " 34" by "34" .

So the new lengths of the enlarged pictures are of dimension "34" by "34" .
